I'm nowhere near being able to udnerstand the talk, but the naive way
of thinking of evaporation of Black Holes is vacuum fluctuations being
"eaten up" at the event horizon. I take it since no event horizon
forms this view no longer holds with this refined theory? Therefore
there is an alternative process for evaporation implied?
